Accord.NET Extensions logo

Accord.NET Extensions is an extension framework for Accord.NET and AForge.NET. The framework sets focus on .NET native array as primary imaging object, offers algorithms build as extensions, and provides unified platform-abstract imaging IO API. The libraries can be grouped as following:

Image processing

  • Accord.Extensions.Imaging.Algorithms package
    Implements image processing algorithms as .NET array extensions including the Accord.NET algorithms.

    Algorithms sample

            </b>
            <br />
            Implements template matching algorithm (~20x faster than conventional sliding window approach).
